No one plans for a biohazard emergency. When San Francisco residents and businesses need help, Four Month Blood Cleanse responds fast, works quietly, and treats every property โ and every person โ with respect.


Four Month Blood Cleanse is a fully licensed and insured Infectious Disease Decontamination company serving San Francisco, CA and the surrounding area. Every technician on our crew is trained, background-checked, and certified to handle biological hazards safely โ and to treat the people affected by them with dignity.
Our San Francisco crew is local โ not a subcontractor pulled from three states away. That means faster arrival times, familiarity with local disposal regulations, and a team that's actually invested in this community.
Beyond the technical side, our San Francisco team understands that a biohazard call almost always comes during a stressful, sometimes traumatic moment. That's why every technician goes through communication training in addition to safety certification โ so you get a crew that's skilled with equipment and calm with people.
San Francisco customers deserve to know exactly what training and equipment a crew is bringing into their home or business. Here's the short version.
We're happy to walk you through our certifications and process over the phone before you commit to anything โ call +1-844-401-0166 and ask any question you have about how we work in San Francisco.
From emergency scenes to scheduled commercial decontamination, our San Francisco crew covers the full range of biohazard response โ always with the same certified process and the same respect for your privacy.
Blood, bodily fluids, or trauma scenes can't wait, and neither do we. Our San Francisco emergency team is dispatched the moment you call, day or night, weekends and holidays included.
We treat every San Francisco home like it's our own โ full sanitation, odor removal, and safe disposal so your family can return to a normal, safe space. We work around your schedule whenever possible.
We work with property managers, offices, warehouses, and industrial facilities across San Francisco to resolve biohazard incidents without disrupting operations any longer than necessary. Our team coordinates directly with facility staff from start to finish.
Some situations call for specialized equipment and protocol. Our San Francisco team handles the harder cases other companies turn away, including jobs that require extended containment or extra sanitation cycles.
No two calls are identical, but most fall into a few categories. Here's a closer look at what our San Francisco team handles on a regular basis.
When a death goes unnoticed for days or longer, biological material can affect flooring, subflooring, and even structural materials. Our San Francisco crew removes affected materials safely and eliminates odor at the source, not just on the surface.
Families in San Francisco facing this kind of loss deserve a crew that works quickly and quietly. We coordinate with law enforcement when needed and complete cleanup once the scene has been released.
Hoarding jobs in San Francisco often involve biological hazards hidden under clutter โ mold, pest waste, and spoiled materials. We sort with care, separate salvageable items when asked, and sanitize the full property.
Raw sewage introduces serious pathogens into a San Francisco home or business fast. We extract contaminated water, disinfect affected materials, and address any lingering odor or moisture risk.
When a property in San Francisco has been exposed to an infectious illness, we perform full surface and airborne decontamination using medical-grade disinfectants to reduce risk for anyone who uses the space next.
Former drug production sites in San Francisco leave behind chemical residue that ordinary cleaning can't remove. Our specialized team tests, treats, and clears the property according to CA remediation standards.
A real person answers your call in San Francisco โ day or night โ and starts dispatching a crew immediately.
Our San Francisco crew arrives in an unmarked vehicle, dressed professionally, to protect your privacy from neighbors and passersby.

We know the cost of Infectious Disease Decontamination services is a real concern. Here's what to expect when it comes to pricing, insurance, and paperwork.
If you have questions about how a specific insurance policy applies to your San Francisco situation, mention it when you call โ our dispatcher can often give you general guidance right away.
We know you're not just comparing prices โ you're trusting someone to handle one of the hardest moments you'll deal with. Here's why San Francisco residents choose us.
You'll know the cost before we begin. We work directly with insurance when possible to reduce your out-of-pocket expense, and we explain every charge in plain language.

Our team documents every step of the job to support your insurance claim, and we bill many major carriers directly to reduce your paperwork.
We don't consider a job finished until the space passes our own internal inspection standard, not just a quick visual check.
Our technicians are trained not just in decontamination, but in how to interact with people on one of their hardest days. That balance matters as much as the equipment we bring.
